Personality type is a powerful tool you can use to improve your relationships and find compatible love. WE have ebooks for each of the 16 personalities to solve the problems you're having in your relationships. Check out our full library below.

Who ISTJs Are Most Compatible With

ISTJ’s personality compatibility is based on the cognitive alignment of the types, their temperament, and their interaction style. ISTJs are as follows:

  • Cognitive functions: Si Te Fi Ne
  • Temperament (Kiersey): Guardians
  • Interaction style (Linda Berens): Chart The Course

There is no perfect 100% compatible match. ISTJs are scored for their compatibility with other personality types based on four factors- communication, passion, friendship, and partnership. A match that is high in one is often lower in another. It is up to the individual to decide which factors are most important for them in a relationship.

Communication

ISTJs have the greatest compatibility in communication with types that share the same cognitive functions. The cognitive functions are like languages our minds speak and when someone has the same functions, we do not have to translate our minds to them. ISTJs speak the languages of past instances and facts. As a result, ISTJs communication compatibility can be broken down as follows:

  • High Compatibility: ISTJ, ESTJ, ENFP, INFP
  • Medium High Compatibility: INTJ, ENTJ, ESFJ, ISFJ
  • Medium Low Compatibility: ISFP, ESFP, ENTP, INTP
  • Low Compatibility: INFJ, ENFJ, ESTP, ISTP
Partnership

For partnership, ISTJs are most compatible with EP types- meaning ENTP, ENFP, ESTP, and ESFP. Together, they are the most efficient and get the most done. The two balance each other out and their working styles do not clash with each other, preventing conflict and complacency.

Friendship

For friendship, ISTJs tend to be compatible with fellow SJ types. This means they have the greatest compatibility for companionship with ISTJs, ESTJs, ESFJs, and ISFJs. These types see the world through a similar lens and so can easily get along and enjoy activities together.

Passion

ISTJs have the greatest amount of passion compatibility in a relationship with those that have opposite cognitive functions to them. For them, ESTPs, ISTPs, ENFJs, and INFJs are polar opposites to them and create a spark. However, this passion can also turn to the most electric fights. These types together are the most likely to resolve their arguments with “physical activities.”

Who are ISTJs least compatible with?

ISTJs have the greatest amount of conflict, and thus least compatibility, with the personality types that have opposite cognitive functions. When two people with opposite perspectives come together, they are bound to conflict eventually. While all couples have arguments no matter what their types, below are some common points of conflict for ISTJs with other personality types.

Incompatibility with FJ types- ESFJ, ISFJ, ENFJ, INFJ
  • The ISTJ’s focus on efficiency can bulldoze over the harmony of the group and other people’s feelings which distresses the FJ. The FJ interprets this behavior as being an “a*-hole”. Conversely, the FJ’s focus on group harmony can forsake efficiency. The ISTJ interprets this behavior as being a pushover or fake to make other people happy. The ISTJ’s directness can hurt the feelings of others. The FJ then feels responsible to clean up the ISTJ’s “mess”. Finally, the FJ’s need to fit in and empathize first can put their own interests and truth at jeopardy. So, the ISTJ feels responsible to clean up the FJ’s “mess”.
Incompatibility with NJ types- ENTJ, INTJ, ENFJ, INFJ
  • NJs are driven to move towards a singular vision for the future. However, ISTJs prefer to maintain their system for what has been done in the past. So, the NJ sees the ISTJ as stuck in their ways. Conversely, the ISTJ sees the NJ as ignoring important details before moving forward.
Incompatibility with TP types- ENTP, INTP, ESTP, ISTP
  • The ISTJ is focused on efficiency and gets frustrated with the TP’s need for understanding which can slow things down. TPs can lack respect for the ISTJ’s lack of depth of understanding a subject. When a ISTJ teaches or tries to explain a concept to a TP, the TP is prone to ask many questions to develop their own internal framework of the subject. The ISTJ sometimes interpret these questions as being dumb or lacking research.

Incompatibility with SP types- ESTP, ISTP, ESFP, ISFP
  • SPs seek to engage with what is actionable in the present in order to move towards a singular Ni vision. Thus, they disrupt the status quo, distressing the ISTJ and making them feel like things are in chaos. The ISTJ maintains the status quo and focuses on the fine details- making the SP feel stifled and trapped.  The SP doesn’t understand why the ISTJ doesn’t want to move forward or “go for it”. The ISTJ views the SP’s approach to the world as haphazard and dangerous.
